Application led'February 25, 1913.

vented certain new and useful lmprovements in Carbureters; and I do hereby declare that the following is a full, clear, and

exact description thereof.

My invention refers tocarbureters, its object being to provide positive means for forcibly breaking up the globules of oil and' distributing the same in a spray, through which spray air is caused to pass, whereby the carbureted mixture is rendered uniform.

To obtain the desired result, l provide a rotor that is located within the carbureter mixing chamber and arranged to receive oil from a suitable source of supply, the said rotor being positively driven by a suitable motor in connection therewith.

lith the above object in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying drawing. and subsequently claimed.

The. accompanying drawing illustrates a sectional elevation of4 a. carbureter embodying the features of my invention.

Referring by" characters to the drawing, l represents a valve-controlled air intake mouth that communicates with a mixin chamber 2, the discharge nozzle 3 of whic is provided with the ordinary regulating valve 4. Extending into the mixing chamber is an oil discharge pipe 5, 'the same being controlled by an Ordinary needle valve 6. rllhis discharge pipecommunicates with a float chamber 7, which float chamber is adapted to contain a predetermined quantity of oil, the said quantity being regulated by a float 8 which is by a suitable lever connected to a pin-valve 9 that controls an oilsupply channel 10. Journaled in suitable bearings with which the mixing chamber is provided is a spindle 11 having one end extending outside of the mixing chamber and to which end is secured a beveled gear-wheel l2. The said gear-wheel l2 meshes with a similar gear-wheel 12 that is secured to the shaft 13 of a motor lll. The oil discharge pipe 5 is provided with a downturncd nipple 3' that is centrally disposed with relation to the mixing chamber, the spindle l1 being in alinement with said nipple. Secured to Speoiiication of Letters Patent.

Serial No. 750,551.,

the upper end of the 'spindle l1` directly under the oil pipe nipple 5 is a disk 15, which disk constitutes a;rotor upon, the face of which oil is discharged'from thepipe 5, the mixing chamber, for convenience, in this exemplification of my invention, being preferably enlarged about the edge of the disk or rotor, whereby a channel for the free passage of air is obtained thereabout.

In' practice air` is admitted through the valve-controlled mouth 1 and travelsupward through the mixing chamberabout the edge of the disk and is discharged in the usual manner. When in operation the spindle 11 of the rotoris positively driven at a high speed by its motor connection and as the oil is fed upon the center disk or rotor in a downward direction it is apparent that it will, by centrifugal force, be thrown outwardly into a fine spray or sheet, through which sheet the air, traveling in the opposite direction, is 4 compelled to travel and thus take up the oil in uniform proportions, the carbureted air being thereby thoroughly mixed before it is admitted to the explosive end of the engine cylinder to obtain the most effective results.

am aware that various rotors have been employed for. mixing the air and oil in carbureters, but, so far as I am aware, heretofore, none ofthe carbureters of this type have utilized a solid rotor in the form of a disk located inthe air chamber to thus restrict tlie air passage and cause the same to travel upwardly about the peripheraledges of the disk. Nor have these devices employed means for discharging oil downwardly upon the center of a solid disk in a direction opposite the flow of air. This construction enables' me to obtain a. new result due to the fact that the oilvstriking the center of the disk must be deflected in a spray uniformly in all directions meeting the peripheral restricted air passing about the edges of said disk, whereby a uniform supply of air passing upward through said passage is brought into contact with the uniform line spray of oil, thus insuring an efficient and even mixture, whereby variations in the fuel mixture are effectually eliminated. It is also apparent that while I have shown and described the rotor as being ingear connection with a prime mover that .I may, without departing from the 'spirit of my invention, connect the rotor direttly to the shaft 0f the prime mover or motor, or, in some instances I may, Without `departing from the spirit-,of my invention,

utilize the power from the internal combustion engine to which the carbureteris ap-V plied.
